From b532b8c65fd1828fd7d742d0994c6118880d07f0 Mon Sep 17 00:00:00 2001 From: Bryan Bell Date: Mon, 12 Jan 2015 16:22:37 -0800 Subject: Add mouse cursor support Add a new api, window.set_cursor, for setting the cursor. The enum MouseCursor lists the possible cursors. Only X11 is implemented. On OSX, Android, & Win32 the window.set_cursor function either does nothing or calls the "unimplemented!" macro. --- src/x11/window/mod.rs | 46 +++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 45 insertions(+), 1 deletion(-) (limited to 'src/x11/window') diff --git a/src/x11/window/mod.rs b/src/x11/window/mod.rs index cff2c61..402beec 100644 --- a/src/x11/window/mod.rs +++ b/src/x11/window/mod.rs @@ -1,4 +1,4 @@ -use {Event, BuilderAttribs}; +use {Event, BuilderAttribs, MouseCursor}; use CreationError; use CreationError::OsError; use libc; @@ -611,4 +611,48 @@ impl Window { pub fn set_window_resize_callback(&mut self, _: Option) { } + + pub fn set_cursor(&self, cursor: MouseCursor) { + unsafe { + use std::ffi::CString; + let cursor_name = match cursor { + MouseCursor::Default => "left_ptr", + MouseCursor::Crosshair => "crosshair", + MouseCursor::Hand => "hand", + MouseCursor::Arrow => "arrow", + MouseCursor::Move => "fleur", + MouseCursor::Text => "xterm", + MouseCursor::Wait => "watch", + MouseCursor::Help => "question_arrow", + MouseCursor::Progress => "watch", // TODO: Find better matching X11 cursor + MouseCursor::EResize => "right_side", + MouseCursor::NResize => "top_side", + MouseCursor::NeResize => "top_right_corner", + MouseCursor::NwResize => "top_left_corner", + MouseCursor::SResize => "bottom_side", + MouseCursor::SeResize => "bottom_right_corner", + MouseCursor::SwResize => "bottom_left_corner", + MouseCursor::WResize => "left_side", + MouseCursor::EwResize => "h_double_arrow", + MouseCursor::NsResize => "v_double_arrow", + + + MouseCursor::NeswResize | MouseCursor::NwseResize => "sizing", // TODO: Better matching X11 cursor + + MouseCursor::ColResize | MouseCursor::RowResize => "double_arrow", // TODO: Better matching X11 cursor + + /// TODO: Find matching X11 cursors + MouseCursor::NotAllowed | MouseCursor::ContextMenu | + MouseCursor::NoneCursor | MouseCursor::Cell | + MouseCursor::VerticalText | MouseCursor::Alias | + MouseCursor::Copy | MouseCursor::NoDrop | MouseCursor::Grab | + MouseCursor::Grabbing | MouseCursor::AllScroll | + MouseCursor::ZoomIn | MouseCursor::ZoomOut => "left_ptr", + }; + let c_string = CString::from_slice(cursor_name.as_bytes()); + let xcursor = ffi::XcursorLibraryLoadCursor(self.x.display, c_string.as_ptr()); + ffi::XDefineCursor (self.x.display, self.x.window, xcursor); + ffi::XFlush(self.x.display); + } + } } -- cgit v1.2.3 From 95f0990074155b1c44c9152f717730d3a1e71776 Mon Sep 17 00:00:00 2001 From: Bryan Bell Date: Mon, 12 Jan 2015 19:00:45 -0800 Subject: Refine X11 cursor selections For MouseCursor::Cell, NotAllowed, NoDrop, Grab, Grabbing, ... set the appropriate X11 cursor.
